Ingredient research · Vitamin C

Vitamin C is an essential water-soluble nutrient that supports collagen production, antioxidant defenses, and the normal function of immune cells. Supplementation reliably prevents or corrects deficiency, can improve absorption of plant-based iron, and may modestly shorten the duration of common colds when taken regularly.

• Supports lower common-cold risk during brief periods of severe physical exercise or cold stress.
• Supports circulating Vitamin C status across studied healthy and clinical populations.
• Supports short-term blood-pressure and endothelial-function outcomes in studied adults.
• Supports fasting-glucose and HbA1c outcomes in adults with type 2 diabetes.

Ingredient research · Quercetin Dihydrate

Quercetin Dihydrate is a crystalline form of quercetin, a plant flavonoid that influences antioxidant and inflammatory pathways. It may modestly support blood pressure and related cardiometabolic measures, while use for allergy symptoms or immune support is less certain; “dihydrate” refers to bound water molecules, not a proven special therapeutic advantage.

• Supports plasma uric-acid levels in studied men with high-normal baseline levels.
• Supports systolic-blood-pressure outcomes in studied adults with cardiometabolic risk.
• Supports HbA1c outcomes in studied adults with type 2 diabetes.

Ingredient research · NAC

NAC is a cysteine derivative that helps replenish glutathione, a major cellular antioxidant, and also thins mucus by breaking bonds in its proteins. As a supplement, it may support antioxidant defenses and respiratory health; acetylcysteine also has established medical uses as a mucolytic and as an antidote for acetaminophen poisoning.

• Supports glutathione and antioxidant-defense measures.
• Supports depressive symptoms and negative symptoms of schizophrenia.
• Supports cannabis-use, craving, and abstinence outcomes.
• Evidence supports kidney-function and injury-marker outcomes in clinical treatment settings.
• Supports hearing-loss and ototoxicity outcomes in noise- and medication-exposure settings.

Ingredient research · Stinging Nettle

Stinging Nettle is an herb used in different forms: root preparations may modestly ease urinary symptoms associated with benign prostate enlargement, while leaf preparations are taken for seasonal allergy or joint complaints. The latter uses remain less established, making the plant part and extract important to what a supplement can plausibly do.
